Solve and graph x+3>2

Answers: 2

Answers

X + 3 > 2

Subtract 3 from both sides to solve for x:

x + 3 - 3 > 2 - 3
x > -1

x > -1 is a vertical line with an undefined slope.

Since any two points on a vertical line have the same x-coordinate, slope cannot be computed as a finite number using the slope formula, because division by zero is an undefined operation. Vertical lines are symbolically represented by the equation, x = a where a is the x-intercept.

To graph, start at x = -1 (you could choose any y-coordinate), then draw a vertical line from that point. Use a dashed boundary line (because of the “ >” symbol). The boundary line separates the rectangular coordinate system into two parts. One of those parts will make the inequality true and be its solution.
Attached is a graph of x > -1.

Solve and graph x+3>2

Answer from: Quest

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
